I had both my kitties "done" at the same time. Graemer the male, and Miley the female. They both spent an overnight at the Vet, in a cage, thus cutting down on the activity. So technically speaking, they were there from 9AM one day, until 5PM the next day....so one night, two days. Miley was a little slow when she first got home but began jumping all around within one more day. Graemer didn't miss a beat. He was active from the time he got home. So if my kitties were uncomfortable at all, I missed seeing it since they were at the Vet during the early recovery time.

Keep us posted.
